The Zarya and Zvezda modules of the International Space Station, as well as Salyut 2, 3 and 5, and the Spektr and Priroda modules of Mir, were launched from Area 23.
On 2 July 2013, a Proton-M/DM-03 launched from Site 81/24 carrying three GLONASS navigation satellites.

On 25 February 2020, Roscosmos announced that Site 81/24 will be deactivated by late 2022 or early 2023; any remaining Proton-M launches on the manifest after that time will be transferred to Site 200/39.
